Title: Controller for hybrid compressor for vehicle
Inventor: TAKANO YOSHIAKI
IPC: B60H1/32
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To easily mount a compressor on a vehicle by making the size of an electric motor small. SOLUTION: When it is judged at a step S90 that a necessary cooling capacity is smaller than a predetermined necessary capacity, the capacity of a compressor is smaller than a predetermined capacity and the amount of circulating coolant is small in a refrigeration cycle and hence a driving force for driving the compressor is small. Therefore, the compressor can be driven by an electric motor having small driving force. When a cooling load is larger than a predetermined value, the capacity of the compressor is larger than a predetermined value and the amount of circulating refrigerant is large in the refrigeration cycle and hence a driving force for driving the compressor is large. Therefore, the compressor is driven by an engine having large driving force.  Accordingly, the compressor can be driven by a small sized electric motor and the electric motor can be easily mounted on a vehicle.

IPC: G11C11/4076
Filed: 1990-09-19
Abstract: PURPOSE:To extend the write margin by providing a second driving voltage raising means which raises the driving voltage again in response to a write control signal. CONSTITUTION:A first driving voltage raising means 3 which is connected to a driving voltage generating means 2 and raises the driving voltage to a value higher than the supply voltage and a second driving voltage raising means 50 which raises the driving voltage again in response to a write control signal WE from a write signal input means 8 are included. Further, a decoder means 1 is included which is connected to a memory cell array and decodes address signals A0 to Ag from an address input means 5 and supplies the raised driving voltage to a word line corresponding to address signals A0 to Ag. Since the second driving voltage raising means 50 raises the level of the word line to the supply voltage or higher in response to the write signal which is given from the write control signal input means 8 at the time of write, the unwritable state is avoided even if the level of the word line falls. Thus, the write margin is extended.

Title: Film for covering transparent plate
Inventor: IGAWA MOTOHARU
IPC: B32B15/08
Filed: 1987-10-06
Abstract: PURPOSE:To eliminate trouble due to the adhesive property of the title film as well as a difficulty for deaerating and facilitate the bonding work of the same film by a method wherein a light shielding film, in which light permeating property remains, is made by either one of a hydrophilic transparent film or a hydrophobic transparent film while water-soluble adhesive agent is coated on the side of the hydrophilic film of a laminate film, made by laminating both films. CONSTITUTION:A hydrophilic transparent film 2 is coated with water-soluble adhesive agent and the same agent is dried, therefore, the whole of a film for covering a transparent plate is dipped into water and is lifted up upon employing to bond it on the transparent plate while the adhesive property of the agent remains. In this case, the water-soluble adhesive agent 3 and the hydrophilic film 2 hold moisture sufficiently, therefore, the film will never be charged with static electricity and curl is hardly generated on the film. Bubbles between the film and a glass plate or the like may be deaerated easily by pushing the film slightly against the glass plate because of a lubricating effect due to water in the watersoluble adhesive agent 3 while the correction of bonding position may also be effected simply. Further, a part of moisture, absorbed into the hydrophilic film 2, remains between the hydrophilic film 2 and the hydrophobic film 1 for a long period of time after bonding the laminated film on the transparent plate, therefore, separation of the film due to excessive drying may be prevented.

Title: Oscillator
Inventor: OTSUTOO RICHIYAADO BIYUURAA
IPC: H03L3/00
Filed: 1988-10-07
Abstract: PURPOSE: To instantaneously start a stable operation of an oscillator by releasing a filter from its initial condition when a transistor amplifier is turned on. CONSTITUTION: When the gate voltage Vin drops less than the reference voltage Vr , a transistor amplifier 16 of a Colpitts oscillator is turned on. Then the current Ic flows to a current path passing through a transistor Tr 41 and the current Ip of a current generation source 40 does not flow to an inductor 12. When Vin >Vr is satisfied, both currents Ic and Ip flow through the inductor 12 and then flow through a Tr 42 and a Tr 43 respectively. When the oscillator is turned on, the inductor 12 generates the voltage in response to the currents flowing into the capacitors 14 and 15. As a result, a stable operation of the oscillator is started without receiving any influence of a switching transient state. Therefore, this sine wave oscillator can instantaneously starts its stable operation by releasing a filter from its initial condition when the amplifier 16 is turned on.
